Christina,
Considering you shot it 20 minutes after sunrise, then it is golden hour. Maybe it would work better in the afternoon (about half an hour before sunset). If you live close to this place, it would be nice to reshoot it and make the comparison. That would be a nice study for your and our learning. The reason for that is it seems, to me, that the light source is quite directed to the camera (again, I can be completely wrong on this!), so in the afternoon you would have the source behind you (and your camera).
Also, although you used 10mm focal length, I would increase shutter speed a little at a price of raising your ISO (you have a darn good sensor for that
) just to avoid any leaves movement/shake due to any wind blowing on them.
I hope this makes any sense...
The second/other image works still better for me! Instead of the vertically centralized composition, this one has a leading line to the vertical third of the image that works pretty nice, IMHO. Well done!
Cheers,
